Application led September 25, 1925. Serial No. 58,540.

My invention relates to radiators and particularly to radiators of the type which may be advantageously employed in automobiles, aeroplanes and the like.

b The invention has among its other ob]ects the production of devices of the kind described which are durable, eilicient and satisfactory for use Wherever found applicable. A particular object of the invention is to provide improved radiator construction which will insure that substantially all of the air passing through the radiator will come in contact with the water tubes.

Many other objects and advantages of the l construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given;

To this end my invention consists in the novel construction, arrangement and combiand more particularly pointed out in the claims.

nation of parts herein shown and described,

Fig. 5 is a section taken on line 5-5 of- Fig. 9 is a section taken on line 9-9 ofy 12, the sides ofthe tubes being flattened as at 13. The plates 11 are bent or folded to provide a plurality of braces or struts 14 extending substantially at right angles to the tubes 10 to provide a plurality of diagonal braces or struts 15, the braces or struts 14 and 15 forming apices 16 to wliichthe tubes 10 are soldered or otherwise secured. The diagonal bracesor struts 15 are stamped to provide a plurality of lips 19 and 20. The lips 19 are formed on the undersides of the struts 15 and point toward either the rear or the front of the radiator. The lips 2O are formed on the upper surfaces of the struts 15 and point either toward the front or the rear of the radiator. Obviously, the lips 19 and 2O Will not impede the air passing through the radiator to any great extent but will cause substantially all of the air to come in 'contact with the tubes 10 or plates 11. It is, of course, understood that the tubes 10 forni Water passages of the radiator. Each lip 19 and 2O is so formed that it will cause air passing through the radiator to pass from one side'of the strut 15 to the other side thereof. This construction insures that the air will flow back and forth between the water tubes so that substantially all of the air may withdraw heat from the tubes. f

The tribes 10 are preferably soldered to the plates 11 by practising my improved method more fully described in my copending application Serial No. 58,542, filed September 25, 1925, the plates 11 being first coated with any suitable substance to which solder will not adhere. This coating is removed from thev apices 16 by means of a wire brush or the like and the tubes and plates are then held in their assembled positions by any suitable temporary means (not shown) and are dipped a short distance into a bath of fused solder so that the solder wi'llflow along the apices 16 to solder them to the adjacent surfaces of the tubes 10. The solder flows along the apics because of capillary attraction but does not adhere to the coated surfaces of the plates, nor does it tend to spread itself over those portions of the tubes disposed intermediate the apices 16.

-In Figs. 4 and 5, I have illustrated another form of the invention embodied in a radiator comprising water tubes 10, which are substantially identical with the aforementioned water tubes 10. The water tubes 10' are soldered to apices 16a formed upon plates 11,

' between the tubes.

which resemble the aforementioned plates 11,

the plates 11 being folded or bent to provide a plurality of strut members 1 5 extending The strut members 15 are stamped to provide a plurality of lips 19 and 20, which face toward the front of the radiator. The lips 20'* project from the uper sides of the strut members 15a and the ips 19a project from the lower sides thereof. The lips 19 and 2,0 function in a manner which is .similar to that in which the aforementioned lips 19 and 20 function. It will be noted that the lips 19a are laterally spaced with'rcspect to the lips 20%.

Figs. 6 and 7 illustrate another form ofthe invention comprising tubes 10 and plates 11" formed in the same manner as the tubes 10 and plates 11, respectively, with the exception that the plates 11b are provided with only two lips 19b and 2Ob which are spaced laterally with respect to each other.

In Figs. 8, 9 and 10, I have shown still another form of the invention embodied in a radiator comprising tubes 10c which are subthe tubes 10. Struck up from each strut 156 are a plurality of blades 20c which are twisted in such manner that they form a complete turn between the front of the radiator and the rear thereof. The blades 20c will, of course, set up a'turbulenee in the air passing through the radiator and cause substantially all of the air to come in contact with the tubes 10c. The tubes 10c may be soldered to the plates 11c by practising the improved method described in the aforementioned co-pendiiig application..

In those forms of the invention illustrated in Figs. 1 to 6,- inclusive, it will be note-d that the lips 19, 20, 19, 20, 19" and 20b are longitudinally arranged with respect to the radiators. The lips do not interfere to any app'reciable extent with the passage of air through the radiator. However, the air is sufficiently deliected as it passes through the radiators so. that there will be a relatively large exchange of heat between the elements of radiators and the air.

Having thus described my invention. it is obvious that various immaterial modificap tions may be made in the same without dei ly straight tubes, Lbent plates having horizontal portions and inclined portions joining opposite ends of said horizontal portions interposed between the tubes for securing them to each other in spaced relation, said plates being separated from the interior of the tubes solely by the thickness 4of the material from which the tubes are constructed, and means formed in the inclined portions of the plates for causing a turbulence in air icient contacts with the tubes and said plates.

2. In a radiator, a plurality of substantially straight tubes, plates having portions eX- tending transversely between said tubes interposed between the tubes for securing them to each other iii/spaced relation, each of said plates having strut-like portions disposed diagonally with respect to the tubes and said transverse portions, and passages formed through said diagonally disposed portions to direct air flowing through the radiator against said tubes and said transverse portions.

3. In a radiator, a plurality of substantially straight tubes, plates interposed between the tubes for securing them to each other in spaced relation, said plates being separated from the tubes solelyT by the thickness of the material from which the tubes are constructed, each of said plates comprising horizontal' portions and strut-like portions disposed diagonally with respect to the tubes and joining opposite ends of said horizontal portions, and passages formed through said diagonally disposed portions to direct air flowing through the radiator against said tubes and said plates.

4. In a radiator, a plurality of substantially straight tubes, plates interposed between the tubes for securing them to each other in spaced relation, each of said plates comprising transverse portions connected to said tubes strut-like portions extending between the tubes, and joining said transverse portions, a spiral-shaped member formed in the strut-like portions for causing a turbulence in air passing through the radiator to bring the air into eiiicient contact with the tubes.

5. In a radiator, a plurality of substantiallv straight tubes, plates interposed between the tubes for securing them to each other in spaced relation, each ot said plates having horizontal portions transversely disposed be- Y tween said tubes and secured to same, and diagonally disposed strut-like portions extend-. ing between said tubes and opposite edges of adjacent horizontal portions, a spiral-shaped portion formed in each strut-like portion for causing a turbulence in air passing through the radiator to bring the air into efficient contact with thetubes and said plates.

In testimony whereof, I have hereunto signed my name. y 'n rARTHUR B. MODINE.
